Patent GB-2137567-A (GB)
Title: Vehicle suspension
Inventor: GALLAGHER JOHN JOSEPH
IPC: B60G21/10
Filed: 1983-04-08
Abstract: In a vehicle suspension wherein the wheels are carried by pistons acting in associated cylinders, the cylinders of a pair of wheels (at one end or side of the vehicle or diagonally opposite) are interconnected such that the upper chamber of each cylinder is piped to the lower chamber of the other cylinder. A valve (Fig. 4) is provided in the interconnection which can be positioned to allow flow between the cylinders, so that suspension movement is equal at each wheel or can be positioned as shown to connect each cylinder's upper chamber with its own lower chamber, thus providing only shock absorption when equalising or levelling is not required. The valve can be operated manually, by turning the steering wheel, by tilt, or by electronic sensor. <IMAGE>
Patent GB-2132095-A (GB)
Title: Ball sorting device in a pool table
Inventor: RIMMER NORMAN LESLIE
IPC: A63D15/00
Filed: 1983-07-29
Abstract: The device consists of a twin ramp having a shallow inclined outer ramp 34 and a steeper inner ramp 35. The ramp 34 leads over an aperture 36 formed in a ball storage rack 32 and the ramp 35 leads to the aperture. Object balls pass to the rack 32 via the outer ramp 34 while the smaller cue ball rolls down the ramp 35 and through the aperture. When all the object balls are on the rack the last racked ball partly obscures the aperture so preventing delivery of the cue ball thereto. <IMAGE>

Title: Baking oven
Inventor: KONIG HELMUT
IPC: A21B1/46
Filed: 1985-01-08
Abstract: A baking oven has a baking chamber (2) in which plate members (5) carrying the baking goods are intermittently conveyed along an endless path. The baking chamber (2) has an opening (4) through which a branch (9) of this endless path if fed to a charging and discharging station (10) located outside of the baking chamber (2). Hot air is blown into the baking chamber (2) by means of a blower (24) and heater (26). In order to prevent hot air within the baking chamber (2) escaping through the charging opening (4), this opening can be closed by a vertically movable valve plate (44) actuated in synchronism with the movement of the plate members (5). Further in synchronism with this actuation, a pivotable lid (62) is actuated which guides the hot air either into the baking chamber (2) when opening (4) is closed or into a by-pass-channel (61) leading back to the blower (24). <IMAGE>

Title: Crop engaging elements, yieldable under an excess load
Inventor: KLINNER WILFRED ERWIN
IPC: A01D82/00
Filed: 1986-02-12
Abstract: A crop engaging rotor for conveying and/or conditioning or otherwise treating crop comprises support members 12 and a plurality of outwardly extending crop engaging elements 11. Each crop engaging element 11 is made of resilient synthetic plastics material and forms two outwardly extending arms 21 and 22 generally in a V-shape. The element 11 is secured to a flange 14 or 14A of a transverse mounting bar 12 which forms part of the rotor. The arms 21 and 22 are yieldable to move rearwardly under excess load conditions by a rocking movement about the bolt 23 of the element as a whole by means of resilient member 24A or by twisting or lateral bending of the arms. The element 11 is prevented from rotating about the bolt 23 by abutment of the leading edge surfaces of the arms 21 and 22 against the inner surface of the upstanding portion 14A of the member 12, and by abutment of the base of the element 11 against the base flange 14 of the member 12. The arms 21 and 22 are linked by a base portion 80 parallel to the upstanding flange 14A (Fig. 1), or by a base portion 84 perpendicular to the upstanding flange 14A in combination with a strengthening web 80 (Fig. 4, not shown). <IMAGE>

Title: Single mode fibre adjustable attenuator
Inventor: SAVAGE DERRICK REGINALD
IPC: G02B6/26
Filed: 1986-04-30
Abstract: An optical fibre adjustable attenuator in which the ends of a pair of single mode optical fibres (1 Fig. 1), 9 are held by clamps secured by brackets (35, 36 Fig. 3) to a sliding platform 27. Each fibre end rests in and is held in alignment by a groove formed by two needles 3, 4 or 7, 8. Optical coupling between the two fibres may be provided by a short loop of fibre (6) which is similarly held by clamps 11, 12 with its ends aligned in the two grooves, but in this instance the clamps do not move with the platform, and hence movement of the platform alters the spacing and hence the optical coupling between the opposed fibre ends. The fibre ends, the needles, the sliding platform and the clamps are all located within a refractive index matching liquid filled containment vessel formed by a base plate (30, Fig. 4) and a cover (46, Fig. 4). <IMAGE>

Title: Staircases built from kit of parts
Inventor: FORD MALCOLM
IPC: E04F11/025
Filed: 1987-06-29
Abstract: A kit of parts for assembling a staircase comprises two carriage members (1) and tread support members (2) each carried by a locating member (3) slidable along the carriage member (1) adjustably to locate the tread support members (2). In the assembled staircase the carriage members are the long load- bearing side members of the staircase carrying the tread support members and the kit can also comprise tread members (4), balusters (7), a hand rail (6) and newel posts (8). Components can be cut to size on site, and the staircase can be assembled in situ, thus avoiding obtaining a custom-built staircase and the attendant problems of fitting such a staircase into position on site. <IMAGE>

Title: Monitoring a pressure fluid pump of a brake system for automotive vehicles
Inventor: SEIBERT WOLDRAM
IPC: B60T8/94
Filed: 1987-09-28
Abstract: To monitor a pressure fluid pump (30) for the fluid supply of an anti-slip hydraulic brake system (Fig. 1, not shown) for an automotive vehicle, there is provided a piston assembly, the one effective surface thereof being influenced by the pressure at the pump outlet (28) and the opposed effective surface thereof being influenced by the pressure in at least one brake circuit line (13, 14). In the presence of sufficient pump pressure, the piston assembly (37, 38) is displaced in opposition to the pressure in the brake line (13, 14), and an operating piston (49) is actuated by means of a conical surface (48), the piston acting upon a monitoring switch (52). The operating piston (49) is also displaceable by the pump pressure in opposition to the force of a compression spring (51), the spring force being so rated that, in the presence of maximum pump pressure, the operating piston (49) is actuatable irrespective of the piston assembly (37, 38). It is thus avoided that the monitoring switch (52) switches back in the event of the pressure in the brake line (13, 14) rising in excess of the maximum pump pressure, during panic braking for example. <IMAGE>

Title: Supervising alarm circuits at a PBX
Inventor: MCMAHON STEPHEN AUGUSTINE
IPC: H04M11/04
Filed: 1987-10-06
Abstract: A micro-computer controlling a PBX provides an alarm function by monitoring loops containing detectors, the micro-computer being switched to and from alarm monitoring mode by codes dialled from an extension. A personal identification may also be required. An alarm condition detected by the micro- computer causes ringing of an alarm bell. One or all of the extensions may also be called. An automatic dialling function may also work its way through a stored list of numbers until a reply is obtained over the exchange line, the nature and location of the alarm being signalled by code or from a voice synthesiser. The alarm can also be recorded on a printer attached to the micro-computer. A door entry phone is also served.
Patent GB-2317767-A (GB)
Title: Radar seeker
Inventor: WINSTONE MARTIN ROBERT
IPC: G01S3/02
Filed: 1987-11-11
Abstract: A radar seeker includes a 4-element antenna and amplitude or phase comparison target location. The azimuth (C and D) and elevation (A and B) elements share two channels alternately by means of azimuth elevation cycling switches (S1, S2, S4). Sum (31) and difference (29) signals are derived from the two channels and then the difference channel is re-distributed (S4) to dedicated azimuth and elevation channels. The shared channels (G, H) are interchanged cyclically (S3, I1, I2) that mismatches between, them are cancelled out. Relative signal transfer errors are thus avoided. The respective switching operations are controlled, in accordance with pulse arrival information by assessor (41). The difference signal may be based upon amplitudes, or upon phases in which case difference circuit (29) is replaced by a phase sensitive detector.
